Description

Technical Field

[0001] The present invention relates to the technical field of accessories for liquid cargo ships, and specifically to an independent high and very high level sensor connecting rod for liquid cargo ships. Background Art

[0002] At present, the high and very high level alarm sensors on the market for liquid cargo ships are all fixedly installed on one or two sensor connecting rods, and the length of the connecting rod is calculated according to the theoretical tank capacity.

[0003] However, due to construction errors in ships, the measured conclusion of the actual tank capacity often differs from the theoretical calculation, resulting in the sensors on the actual ship not being accurately installed at the 95% (high level) or 98% (very high level) height positions. The alarm deviation of some ships even reaches 1%, and the protection function that the alarm system should perform cannot be achieved at all, and it affects the operation of the ship. Summary of the Invention

[0004] The purpose of the present invention is to provide an independent high and very high level sensor connecting rod for liquid cargo ships to solve the problem that the installation heights of the 98% and 95% independent alarm sensors in the liquid cargo tank are inaccurate as mentioned in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An independent high and very high level sensor connecting rod for liquid cargo ships, comprising: a high level sensor mounting plate, a connecting rod, a very high level sensor, and a pressing rod. An installation seat is provided at the top of the connecting rod. A high level sensor mounting plate is provided at the lower half of one side of the connecting rod. A high level sensor is provided on one side of the high level sensor mounting plate. A very high level sensor mounting plate is provided at the upper half of one side of the connecting rod. A very high level sensor is provided on one side of the very high level sensor mounting plate. A positioning elastic piece is provided on one side of the outer walls of the very high level sensor and the high level sensor. A pressing rod is provided at one side of the bottom of the installation seat, and positioning teeth are provided on the outer wall of one side of the pressing rod.

[0006] Preferably, an installation flange is provided at the top of the installation seat. A relief groove is provided at the bottom of the installation seat at the position where the pressing rod is installed, and a sliding groove is provided at the top of the relief groove at the bottom of the installation seat.

[0007] Preferably, a compression spring is provided at one side of the top of the pressing rod, and the end of the compression spring away from the pressing rod is fixedly connected to the inner wall of the bottom of the installation seat.

[0008] Preferably, adjustment teeth are provided around the outer walls of the high level sensor mounting plate and the very high level sensor mounting plate.

[0009] Preferably, an arc is provided on one side of the pressing rod close to the high level sensor mounting plate, and a tooth groove is provided on the inner wall of the arc part of the pressing rod.

[0010] Preferably, one side of the pressure rod close to the high-high position sensor mounting disc is provided with an arc, and the inner wall of the arc part of the pressure rod is provided with a tooth groove.

[0011] Preferably, scale lines are engraved on the outer wall of one side of the pressure rod from top to bottom.

[0012] Preferably, one of the positioning elastic pieces is connected to the high position sensor through a ratchet, and the other positioning elastic piece is connected to the high-high position sensor through a ratchet.

[0013] Preferably, sliders are provided at the connection parts of both sides of the top of the pressure rod and the mounting seat.

[0014] Preferably, the compression spring is always in a compressed state.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] By setting the high position sensor mounting disc, high-high position sensor mounting disc and pressure rod, the present invention realizes that when the independent high-high position sensor connecting rod of the liquid cargo ship is used, the mounting flange of the mounting seat is fixed to the top of the cabin through screws. When the height of the high position sensor needs to be adjusted, by rotating the high position sensor mounting disc clockwise, since the high position sensor is installed at the eccentric part of the high position sensor mounting disc, during the rotation process, the height will decrease. When the high position sensor mounting disc is rotated counterclockwise, the high position sensor will rise accordingly. During the rising or falling process of the high position sensor, the positioning elastic piece and the high position sensor are connected through a ratchet. At this time, the positioning elastic piece will rise or fall together with the high position sensor. Through the positioning of the positioning elastic piece and the positioning teeth, and in cooperation with the scale lines on the pressure rod, the position of the high position sensor can be quickly determined. During the adjustment process, when the high position sensor mounting disc rotates, the adjustment teeth on the high position sensor mounting disc are misaligned with the tooth grooves on the arc of the pressure rod. At this time, the pressure rod moves under force, and the compression spring is further compressed. The pressure rod generates an offset under the guidance of the chute. When the adjustment is completed, the pressure rod automatically returns to its original position under the compression of the compression spring. At this time, the tooth groove on the pressure rod automatically meshes with the adjustment teeth on the high position sensor mounting disc to limit the angle of the high position sensor mounting disc and prevent the high position sensor mounting disc from rotating, thereby limiting the height of the high position sensor. Similarly, the height of the high-high position sensor is adjusted to ensure the accurate height of the high position sensor and the high-high position sensor, ensure the accurate liquid level alarm in the cabin. During the whole adjustment process, the positioning is accurate, the identification is convenient. After the adjustment is completed, through the elastic compression of the pressure rod and the auxiliary compression of the positioning elastic piece, in cooperation with the damping rotating shaft design of the high position sensor mounting disc and the high-high position sensor mounting disc itself, the position of the sensor is not easy to change, preventing the impact on the sensor during the transportation of liquid materials and causing the change of the sensor position, and ensuring the stability of the liquid level alarm system.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-3 , the present invention provides a technical solution: an independent high and ultra-high-level sensor connecting rod for a liquid cargo ship, including: a high-level sensor mounting disc 1, a connecting rod 2, an ultra-high-level sensor 4, and a pressing rod 6. The top of the connecting rod 2 is welded with a mounting seat 5. One lower half of one side of the connecting rod 2 is rotatably connected to a high-level sensor mounting disc 1 through a damping rotating shaft. One side of the high-level sensor mounting disc 1 is clamped with a high-level sensor 9. One upper half of one side of the connecting rod 2 is rotatably connected to an ultra-high-level sensor mounting disc 3 through a damping rotating shaft. One side of the ultra-high-level sensor mounting disc 3 is clamped with an ultra-high-level sensor 4. One side of the outer walls of the ultra-high-level sensor 4 and the high-level sensor 9 is rotatably connected to a positioning spring piece 7 through a ratchet hinge. One side of the bottom of the mounting seat 5 is slidably connected to a pressing rod 6, and a positioning tooth 8 is processed on the outer wall of one side of the pressing rod 6.

[0023] The top of the mounting seat 5 is processed with a mounting flange 501. A retreat groove is provided at the bottom of the mounting seat 5 at the mounting position of the pressing rod 6, and a chute 502 is provided at the top of the retreat groove at the bottom of the mounting seat 5.

[0024] One side of the top of the pressing rod 6 is welded with a compression spring 601, and one end of the compression spring 601 away from the pressing rod 6 is fixedly connected to the inner wall of the bottom of the mounting seat 5.

[0025] The outer wall of the high-position sensor mounting disc 1 and the high-high-position sensor mounting disc 3 is provided with adjustment teeth around the circumference. The side of the pressure rod 6 close to the high-position sensor mounting disc 1 is provided with an arc, and the inner wall of the arc part of the pressure rod 6 is provided with a tooth groove, which is convenient for meshing with the adjustment teeth on the high-position sensor mounting disc 1, so as to limit the angle of the high-position sensor mounting disc 1.

[0026] The side of the pressure rod 6 close to the high-high-position sensor mounting disc 3 is provided with an arc, and the inner wall of the arc part of the pressure rod 6 is provided with a tooth groove, which is convenient for meshing with the adjustment teeth on the high-high-position sensor mounting disc 3, so as to limit the angle of the high-high-position sensor mounting disc 3.

[0027] The outer wall of one side of the pressure rod 6 is engraved with scale lines from top to bottom, which is convenient for observation during height adjustment.

[0028] A positioning spring piece 7 is connected to the high-position sensor 9 through a ratchet, which is convenient for the rotation of the positioning spring piece 7. Another positioning spring piece 7 is connected to the high-high-position sensor 4 through a ratchet. Sliders are provided at the connection parts of both sides of the top of the pressure rod 6 and the mounting seat 5, which are used to cooperate with the sliding groove 502. While realizing the support of the pressure rod 6, it is convenient for the guiding when the pressure rod 6 deflects, and the compression spring 601 is always in a compressed state.

[0029] Working principle: When the connecting rod of the independent high-position high-level sensor of the liquid cargo ship is in use, the mounting flange 501 of the mounting base 5 is fixed to the top of the cabin through screws. When it is necessary to adjust the height of the high-level sensor 9, by rotating the high-level sensor mounting disc 1 clockwise, since the high-level sensor 9 is installed at the eccentric part of the high-level sensor mounting disc 1, during the rotation process, the height will decrease. When rotating the high-level sensor mounting disc 1 counterclockwise, the high-level sensor 9 will rise accordingly. During the rising or falling process of the high-level sensor 9, the positioning elastic piece 7 is connected to the high-level sensor 9 through a ratchet. At this time, the positioning elastic piece 7 rises or falls together with the high-level sensor 9. Through the positioning of the positioning elastic piece 7 and the positioning teeth 8, and in cooperation with the scale line on the pressure rod 6, the position of the high-level sensor 9 can be quickly determined. During the adjustment process, the high-level sensor mounting disc 1 rotates, and the adjustment teeth on the high-level sensor mounting disc 1 are misaligned with the tooth grooves on the arc of the pressure rod 6. At this time, the pressure rod 6 moves under force, and the compression spring 601 is further compressed. The pressure rod 6 deflects under the guidance of the sliding groove 502. When the adjustment is completed, the pressure rod 6 automatically returns to its original position under the compression of the compression spring 601. At this time, the tooth groove on the pressure rod 6 automatically meshes with the adjustment teeth on the high-level sensor mounting disc 1 to limit the angle of the high-level sensor mounting disc 1 and prevent the high-level sensor mounting disc 1 from rotating, thereby limiting the height of the high-level sensor 9. Similarly, the height of the high-high-level sensor 4 is adjusted to ensure the accurate height of the high-level sensor 9 and the high-high-level sensor 4, and ensure accurate liquid level alarm in the cabin. The entire adjustment process is accurately positioned and easy to identify. After the adjustment is completed, through the elastic compression of the pressure rod 6 and the auxiliary compression of the positioning elastic piece 7, in cooperation with the damping rotating shaft design of the high-level sensor mounting disc 1 and the high-high-level sensor mounting disc 3 itself, the position of the sensor is not easily changed, preventing the impact on the sensor during the transportation of liquid materials and causing the change of the sensor position, ensuring the stability of the liquid level alarm system.
